WARP-BEAM.

To all whom it may concern:

Be it known that I, JAMES Knn'roN, a citizen of the United States, and a resident of New York city, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Tarp-Beams, of which the following is a specification.

This invention relates to improvements in warp beams especially adapted for use in connection with fast warp knitting machines and has particular application to a sectional beam preferably constructed of a suitable light metal, such as aluminum, or the like, although I wish it to be understood that I do not limit myself to the use of this precise material. Since it is essential in the use of warp beams that a perfect tension be maintained on the threads as they are fed from the beam to the needles of the knitting machine, and since the tension must be as light as possible to avoid the danger of breaking of the threads, especially when silk is the material used, the construction of the beams in as light a manner as possible consistent with the required strength is of the highest importance. Furthermore, it has heretofore been the common practice in the construction of knitting machines with which I have been familiar, to form the beams of cylindrical sections of tin soldered together to gain the desired length, the heads being made of cast iron and provided with projecting iron arbors or stud shafts; a beam so constructed is of great weight and in use it is found to be impossible to prevent the working out of the solder which upon coming in contact with the silk wound on the beam renders the same unfit for use, there resulting a great loss in time and labor and cost of silk. Also in forming a continuous beam from sections the same have been commonly coupled together in such a manner that the bearing surfaces of the coupling are liable to wear, there resulting a play be tween the sections rendering impossible the smooth and uniform turning of the assembled beam as a whole.

In carrying out my invention, one of the purposes is to construct the beam of a series of sections each section being built up of detachable parts secured together without the use of solder, rivets or the like, all the sections being adapted to be joined together by a novel form of coupling to form a rela- Specification of Letters Patent.

tively long and complete beam. As is the common practice, the assembled beam is supported in suitable bearings or journals at its ends and at the points of coupling between sections.

Referring now to the accompanying drawings in detail, Figure 1 is a side view partly in elevation and partly in section, showing a warp beam embodying my improvements, together with its end bearings; Fig. 2 is an edge view of one of the ends of the section of the beam, and carrying a key; Fig. 3 is a face view of one of the ends of the beam section, said view being taken on the line 33 of Fig. 1 looking in the direction of the arrow, the connecting pin being omitted; Fig. 4: is a similar view of the opposite side of the end, or that side adapted to receive a cylinder portion of the beam, such View being taken on the line 4El of Fig. 1 and looking in the direction of the arrow with the connecting pin or key likewise omitted.

Referring to the accompanying drawings in detail, 5*5 indicate the end bearings of the beam which may be of any suitable type and adapted to receive the ends 66 of the shaft. The beam may be made up of any suitable number of sections. In the present instance, by way of example, I have shown the beam formed of two sections, the section A and the section B which are adapted to be connected together. The section A comprises the central or cylindrical end members or faces 7 and 8. The member 7, which carries one of the bearing studs or shafts 6, being provided with a threaded extension as shown in Fig. 2 adapted to screw into the adjacent end of the cylindrical part 5, the surface of the end 7 adjacent to this extension being preferably grooved to receive the end of the part 5. At its opposite end the cylindrical portion 5 is also interiorly threaded as is shown at 9, to receive the threaded extension 10 of the side member 8, said threaded extension 10 being secured to the face 8 by means of bolts or otherwise, as shown at 11. Passing through the extension 10 is the pin or bolt 12 slotted as at 13, for the reception of the cross key 14, the end of the pin being tapered as at 15. Pin or bolt 12 is provided with a collar or flange 16 adapted to abut the face of the member 8, the pin or bolt being removably secured in position in said member by means of a nut on its inner end. This construction is shown more clearly in Fig. 2.

A flange 17 is carried by the face or end member 18 of the adjacent beam section B, the flanges 16 and 17 are spacing flanges as is usual, a suitable supporting journal or bearing may be provided between the collars or flanges l6 and 17 for the pin or bolt 12. As this bearing forms no part of my present invention, I do not describe or illustrate the same.

The outer or exterior face of the side member 18 of the section B is shown in detail in Fig. 8, and it will be noted that said face at the collar 17 is slotted as at 19 to permit the passage of the pin and key. The keyway 19 passes entirely through the threaded extension 20 on the inner face of the end 18, this threaded extension being adapted to be screwed into the threaded end 21 of the cylindrical part 22 of the section B. The interior face of the end 18 is also circumferentially grooved as shown at 23-see Fig. 1-to socket the end of the cylindrical section 22. At its opposite end this cylindrical section is threaded onto the end or face member 7 but as this face member is similar in construction and location of its parts to the end member 7, a detailed description of which has heretofore been given, it is unnecessary to reiterate in detail its structural features.

From the above description taken in connection with the accompanying drawings, the construction and operation of the beam will be readily apparent. The various sections are oined together, as shown at Fig. 1, by means of my novel form of coupling which provides a relatively large bearing surface by the use of a key, thus greatly reducing the tendency of the bearing surfaces to wear and the consequent danger of irregular or uneven rotation of beam sections, and when the entire beam is assembled it may be suitably mounted in its bearings. It will be noted that instead of coupling the relatively long, continuous beam, such as now commonly in use, I provide a beam preferably formed of some suitable light material such as aluminum, before mentioned, and also form a beam in sections, so that it may be constructed of any length and the parts may be readily assembled and detached at will.

While I have herein shown and described one embodiment of my invention, I wish it to be understood that I do not limit myself to the precise details of construction, but that variation and modification may be made without departing from the spirit of my invention or exceeding the scope of the claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

l. A beam of the class described, including in combination a plurality of sections, each section comprising a hollow cylindrical mem ber, and end members removably secured in the cylindrical member, and a coupling for connecting the adjacent end members of the sections comprising a pin seated in an opening in one of the end members, a stop and a clamping nut on the pin for engaging the end member to clamp the pin in position, said pin having a transverse key adapted to enter a slot formed in the end member of another section.

2. A beam of the class described, including in combination a plurality of sections, each section comprising a hollow cylindrical member, and end members removably secured in the cylindrical member, and a coupling for connecting the adjacent end members of the sections comprising a pin seated in an opening in one of the end members, a stop and a clamping nut on the pin for engaging the end member to clamp the pin in position, said pin being formed at its free end with an angular face adapted to enter a correspondingly shaped recess in the end member of another section whereby the sections are coupled.

3. A beam of the class described, includ ing in combination a plurality of sections, each section comprising a hollow cylin drical member, and end members removably secured in the cylindrical members, one of said end members having a central opening, a coupling pin having a collar thereon and adapted to be projected through said opening, the collar abutting the outer end member, a clamping nut on the end of the bolt projected through the opening and adapted to engage the inner face of the end member, a slot formed in the end member of the adjacent section, and a transverse member on the bolt adapted to enter said slot whereby the sections are coupled.
